It is summer storm season. And Hollywood is taking full advantage of that severe weather. Natural disasters are actually great for the box office. But how closely do these movies really mirror reality? I've been in storms all my life. And this one is bigger than any storm that has ever been. Reporter: "Into the storm" hits box offices tomorrow, depicting a devastating category 6 tornado. Winds higher than anything ever recorded. This movie is just kind of roughly based on different storms that have hit the united States throughout history. Ultimately culminating in an ef-6 tornado, which has not ever hit the United States. But in this movie, it's what would happen if one did. Reporter: Well, our chief meteorologist says not so fast. Category 6 or an ef-6. These are something we don't have in science. Reporter: Why does it seem as though storms are getting more severe? A big part of it seeming like there are more severe storms is how we see them. We have technology. We have cell phones. We share every hailstone and every tornado. And everybody sees it. Reporter: But nothing quite so dramatic as a wet storm going up in flames. When you have a tornado, all that condensation, water and fire don't go together. That would not be scientifically possible. Reporter: For now, feel free to enjoy the not-so-natural visual spectacle. Special effects were awesome. It's all real natural phenomenon that is horrific, devastating and yet beautiful all at the same time. Reporter: You can relax and grab the popcorn.
